Abstract: The present invention relates to a method and an apparatus for generating an executable file of a multi-instance service. The method includes: performing compilation for a source file corresponding to a multi-instance service, to obtain a first-class object file, where the multi-instance service includes N instances, and N is a natural number greater than or equal to 2; performing an object copy of the first-class object file N?1 times, to obtain N?1 new first-class object files; and performing linking to the first-class object file and the N?1 new first-class object files, to generate an executable file. In the present invention, an executable file is generated by performing mirroring and linking processing for an object file obtained by compilation, thereby reducing a development cost and a maintenance cost of software source code.

Abstract: The present invention discloses a low-power startup method and a user equipment. The method includes: running, by a user equipment UE, a first subprogram in a boot load program bootloader, so as to determine whether the UE is charged through a universal serial bus interface USB; if the UE is charged through the USB and battery power is lower than a starting threshold, initializing, by the UE, the USB; when the USB successfully enumerates the UE, running, by the UE, a second subprogram in the bootloader to initialize an off-chip random memory in the UE; running, by the UE, a third subprogram in the bootloader to read a system mirror from an off-chip flash memory in the UE and load the system mirror to the off-chip random memory; and running, by the UE, the system mirror to complete a startup.

Abstract: Embodiments of the present invention disclose a network switching method, a version upgrade method, and a terminal device, which relate to the field of communications technologies. A terminal receives a user instruction that instructs the terminal to access a network of a target operator. If an operator of a network currently accessed by the terminal is different from the target operator, a preset file is read to obtain image information corresponding to the target operator. A target image file corresponding to the target operator is obtained according to the image information and version switching is performed according to the target image file. The preset file includes image information that corresponds to all image files of operators stored in the terminal in one-to-one correspondence.
